T0 ctZZ whom it 71mg concern.-

Be it known that 1, WILLIAM JAMES HAY- DEN, a citizen of the United States, residing at Athol Center, in the county of Worcester and State of Massachusetts, have invented a new and useful Mortising-Hachine Attachment, of which the following is a specification.

This invention relates to mortising-machines of that character utilizing chain-cutters and which are employed for mortising stiles, &c., and the invention is more particularly an attachment for such machines, by the use of which any number of stiles can be mortised at predetermined points thereon without the necessity of marking them off and exercising care in properly placing them under the cutter.

Heretofore in the manufacture of shutterstiles and similar objects it has been necessary in order to properly mortise them to first lay off the mortise and then carefully place the stile in proper position beneath the cutting-tool, so as to insure the proper location of the mortise. With the present invention, however, after a proper adjustment of the attachment a stile can be placed upon the bed of the machine and fed forward without the exercise of any particular skill and said stile will be held at proper points, so that mortises will be cut thereinto without the necessity of marking off the stiles or exercising any particular care in properly placing them.

Another object of this invention is to provide a novel arrangement of parts whereby mortises of different lengths may be out within a stile at any points desired.

WVith these and other objects in view the invention consists of certain novel features of construction and combinations of parts, which will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings, Figure 1 is a perspective view of a portion of a mortising-machine having my improved attachment applied thereto, said attachment being broken away. Fig. 2 is a plan view of the attachment, the adjoining portion of the machine being in section and the intermediate parts of the attachment being removed. Fig. 3 is arear elevation of the attachment, a portion of the slide and the bed being shown in section. Fig. 4 is an end view of a portion of the table of the machine and the slide and the parts connected thereto. Fig. 5 is a perspective view of the latch. Figs. 6, 7,8, 9, 10, 11,12, and13 are detail views showing the successive steps followed in the passage of a double stop through thelatch and Fig. 14 is a perspective view of a finished stile, showing mortises of different lengths therein.

Referring to the -figures by characters of reference, 1 is the bed of a mortising-machine of the usual construction, the same having a rear upwardlyextending portion 2, and supported above the bed is a suitably-actuated cutting-chain 3. This bed, as usual, is vertically movable so as to carry a stile from or toward the cutting-chain, and a support 4 is disposed in rear of the table. These parts all constituteielements of the ordinary mortising-machines utilizing cutting-chains, and the present invention is in the form of an attachment for use in connection therewith. Hcretofore it has been necessary to mark upon a stile the point or points at which mortises are to be cut, after which the stile is placed on the table 1 with the marks directly under the cutting-chain and the table then moved toward said chain so that the mortise will be out within the stile. Obviously with this construction considerable care must be exercised and time expended in marking off the mortises and in properly placing the stile on the table. The present invention consists of an attachment which obviates these objectionable features and consists of two primary elements to wit, a bed attachment A and a latch attachment B. The bed attachment consists of an elongated dovetailed guide-strip 5, which is secured to the back 2 of the table 1 in any preferred manner and on which is mounted a slide 6, which may be of substantially the same length as the stile to be mortised, although it is of course to be understood that this length is not essential. Secured to the slide 6 adjacent one end is a stop-block 7, the inner or working face of which is concave, as shown at 8, so as to tightly engage the end of a stile and prevent it from being thrown from the table while the cutting-chain is working upon it. The slide 6 projects above the back 2, and secured to the rear face of this upwardly-projecting portion is a longitudinally-extending rod 9, having its ends secured in brackets 10, extending from the slide 6. Adjustably mounted on the rod 9 are a suitable number of stops, which may be of different forms to produce diflerent results.

in the same manner by placing three single stops close together upon the rod, or if preferred, such a stop may be formed in a single piece, as shown at 15, the same consisting of a sleeve 16, provided with three projecting fingers 17, said sleeve being ada ted to be fastened upon the rod by means set-screws 18. It will of course be understood that these stops may be placed at any desired points upon the rod 9, their relative positions and their character being dependent upon the distances apart at which the mortises are to be made and the sizes of the mortises.

As hereinafter explained, a single stop will result in the formation of a short mortise, a double stop a larger mortise, &c., the size of the mortise increasing with the number of stops used together.

The bed attachment A, which has been described, is adapted to be used upon a mortising-machine in connection with a latch attachment B of peculiar construction. This latch attachment consists of an angular plate 19, constituting the base of the attachment and which. is adapted to be fastened by means of bolts 20 or in any other preferred manner to the support 4 of the machine. A guide-flange 21 extends forward from one edge of the front face of the base 19 and upward from said base, and the lower end of this flange has one face beveled, as shown at 22, while its other face has an angular recess 23, adapted to receive the upper end of a strip 24, which is loosely secured, as shown at 25, to one end of a weight 26. This weight is pivoted, as at 27, upon the base 19 and has an upwardly-extending lug 28, adapted to normally bear against a stop-pin 29, and when the weight is in this position the upper end of the stri 24 is disposed at a point slightly removed from the flange 21, as shown particularly in Figs. 5, 6., 12, and 13. This latch is so disposed upon the fixed support 4 that when the bed is in its lowest position the stops 11, 14, and 15 are in position to pass between the flange 21 and the weight 26.

In using this machine the stops are disposed upon the rod 9 at distances apart equal to the distances between the mortises to be formed within a stile, and if a short mortise is to be formed one stop 11 is placed at the proper point upon the rod 9, whereas if longer mortises are to be cut double or triple stops are secured upon the rod at the proper places. In the present instance I have shown a single, a double, and a triple stop arranged upon the rod so as to form a stile 30, having a short mortise 31 in one end, a long mortise 32 in the other end, and a mortise 33 of medium length located at a point between the ends of the stile. In forming a mortise of this character table 1 is lowered, and the slide 6 is drawn toward the right of the machine upon the guide-strip 5, and the stops will successively pass over the weight 26 and against the upwardly-extending portion of the strip 24, swinging said strip downward out of their way, so that all of the stops can assume positions to the right of the latch. A stile is then placed upon the bed 1 and against the block 7 and pushed forward or toward the left of the machine, carrying the slide 6 therewith. This movement will be stopped by the first finger 17 of stop 15 coming into contact with the latch-strip 24, swinging it forward into the recesses 23, these positions of the parts being shown in Figs. 6 and 7. The machine is then set in motion, and the bed is immediately raised, carrying the stop upward in the direction of the arrow in Fig. 7 and along the flange 21, and during this upward movement the chain 3 will cut into the slide. As soon as the stop passes on to the flange 21 the strip 24 swings back to its normal position, as shown in Fig. 8, and when the stop moves downward with the bed after the mortise has been cut and, as shown by an arrow in Fig. 8, the first finger thereof will pass over'the strip 24 and under the flange 21, and a further push upon the slide 6 will bring the next finger against the strip 24 and force said strip against the flange, as shown in Fig. 10. The two fingers 17 will then pass upward upon the flange 21, one of them being disposed at each side thereof, as shown in Fig. 10, and as they pass upward the cutting-chain will again pass into the stile and elongate the first mortise. WVhen the stops come down after this cutting has been completed, they will pass under the flange 21, as shown in Fig. 12, and if other fingers are formed upon the stop the operation can be continued. After the last finger of the stop has passed'under the flange 21 the operator pushes the slide longitudinally toward the left until the finger of the next stop contacts with the latch, whereupon the described operation is repeated.

In Figs. 6 to 13 a double stop only has been illustrated; but the operation of a single or triple stop or, in fact, a stop having any number of fingers will, it is thought, be clearly apparent from an examination of said figures in connection with the foregoing description. It will be noticed that after the stops have once been arranged it is merely necessary for the operator to exert a constant longitudinal pressure upon the slide 6 and the stops will automatically hold the stile at the proper points and for the desired number of cuts, so that mortises will be produced at the proper points and of predetermined lengths. It will be understood that the arm IIO 24 of the strip 24 constitutes a weight and serves to hold said strip by gravity normally removed from flange 21.

The preferred form of the invention has been set forth in the foregoing descrip tion; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of the claims.
